Rapid roll changing mechanism

Abstract

The invention relates to a rapid roller changing mechanism. The rapid roller changing mechanism comprises a rack, the rack is provided with a power mechanism and a steam locking mechanism, the power mechanism comprises a tensioning assembly, the tensioning assembly can drive a tensioning pulley to move so that the tensioning pulley can pull a transmission synchronous belt, so that the transmission synchronous belt is in meshed connection with a tooth roller pulley, a transmission shaft of a transmission motor rotates, trough transmission of a transition synchronous belt, the transmission synchronous belt drives the tooth roller pulley to rotate, namely, an upper tooth roller and a lower tooth roller can be driven to rotate, when the tooth rollers need to be replaced, the tensioning assembly drives the tensioning pulley to reset, the transmission synchronous belt is loosened, the tooth rollers can be moved away for the tooth roller replacing procedure when the transmission synchronous belt is not in meshed connection with the tooth roller pulley, consumed time is short, the roller replacing efficiency is high, after steam in a drainage metal hose is completely discharged, an upper valve body and a lower valve body can be separated, the defects that the rollers can be rapidly replaced without detaching steam inlet and drainage metal hoses, and scalding is prone to occurring are overcome, a conveying trolley is arranged below the rack, the tooth rollers are conveyed through the conveying trolley, and the roller replacing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of shaft changing equipment, in particular to a quick roller changing mechanism. Background technique [0002] The existing toothed roller transmission mechanism includes a motor and a reducer, the toothed roller is connected to the frame in rotation, the motor and the reducer are driven by a belt, and the toothed roller and the output shaft of the reducer are connected by a universal joint coupling. When it is necessary to change the toothed rollers, the universal joint coupling connecting the toothed rollers must be disassembled manually with the help of tools, and then the toothed rollers can be removed for the toothed roller replacement process. The efficiency is low. In addition, when the toothed roller needs to be replaced, the steam inlet metal hose and the drainage metal hose connected to the upper and lower toothed rollers must be disassembled before the roller can be replaced. The existing toothed ...

[0002] The existing toothed roller transmission mechanism includes a motor and a reducer, the toothed roller is connected to the frame in rotation, the motor and the reducer are driven by a belt, and the toothed roller and the output shaft of the reducer are connected by a universal joint coupling. When it is necessary to change the toothed rollers, the universal joint coupling connecting the toothed rollers must be disassembled manually with the help of tools, and then the toothed rollers can be removed for the toothed roller replacement process. The efficiency is low. In addition, when the toothed roller needs to be replaced, the steam inlet metal hose and the drainage metal hose connected to the upper and lower toothed rollers must be disassembled before the roller can be replaced. The existing toothed roller and the steam inlet metal hose and the drainage The metal hoses are connected by pipe joints. When disassembling the metal hoses for steam intake, exhaust, and drainage, manual tools are required to remove the connection. The temperature of the outer wall is relatively high. When disassembling the metal hoses for steam inlet and exhaust, it is necessary to wait until the steam in the metal hoses for inlet and exhaust steam has been exhausted and cooled down before disassembling. Otherwise, it is easy to accidentally touch the metal hoses during manual operation. Burning, long time-consuming, affect the efficiency of changing rolls, in order to improve the above shortcomings, it is necessary to make improvements to the existing technology
